  This 
  insect 
  is 
  similar 
  in 
  form 
  and 
  size 
  to 
  the 
  preceding, 
  being, 
  how- 
  

   ever, 
  longer 
  and 
  a 
  little 
  narrower. 
  It 
  is 
  blackish 
  brown 
  with 
  a 
  very 
  

   narrow 
  yellow 
  border 
  at 
  each 
  side, 
  the

  and 
  the

   of 
  the

  red. 
  Their 
  antennae 
  are 
  red 
  ringed 
  with 
  white. 
  

  

  This 
  is 
  a 
  common 
  species, 
  less 
  abundant 
  than 
  the 
  tarnished 
  plant- 
  

   bug, 
  but 
  extremely 
  like 
  it 
  in 
  its 
  economic 
  relations. 
  It 
  continues 
  

   throughout 
  the 
  season 
  until 
  October.
